Hybrid Axles
The Challenge
- Independent highly dynamic movements both axial and also rotative (rotations > 360°)
- Axial force >= 14 kN, Frequency > 30Hz, lift up to +/- 20 mm
- Motor rated torque = 200 Nm, rated speed = 400 rpm
- Speed-overlaid frequency up to 25Hz, amplitude up to +/- 12°
- No wear on the entire drive also for micro movements
The Solution by FGB
- Combined lift-turn unit comprising an E-motor and a hydraulic cylinder
- Rotor is also part of the hydraulic cylinder
- Hydrostatic bearings of the rotor/cylinder
- Development of a wear-free encoder for a linear lifting range of +/- 20 mm
